Compare and contrast photosynthesis and chemosynthesis. Fill in the blank(s) with the appropriate word(s)
In photosynthesis, energy from sunlight is used to bond six separate carbon atoms (derived
from carbon dioxide) into a single energy-rich six-carbon molecule of the sugar glucose. The
pigment chlorophyll absorbs and briefly stores the light energy needed to drive the reactions.
Water is broken down in the process, and oxygen is released. In contrast, chemosynthesis,
employed by some species of bacteria and archaea, is the biological conversion of simple
carbon molecules (usually carbon dioxide or methane) into carbohydrate, using the oxidation
of inorganic molecules (such as hydrogen gas or hydrogen sulfide or methane) as a source of
energy. No sunlight is required.
